NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 268,180, dated October17, 1882.

Application filed March 28, 1882.

T 0 all whom it may concern:

Be it known that I, WILLIAM P. MiLLER, of Tipton, in the county ofMoniteau and State of Missouri, have invented a new and ImprovedNut-Lock, of which the following is a full, clear, and exactdescription.

My invention relates to. improvements in nut-locks; anditconsistsiuanovel construction and combination of parts, as hereinafter more fullyset forth.

The plate to which the swinging plate is hinged is provided with twospring-tongues having guide-loops at the ends, between which a hingedjoint on the swinging plate passes, this hinge-joint being provided witha cam, projection, by means of which and the springtongues the swingingplate can be held in any desired position.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding pa'rts in all the figures.

Figure 1 is a perspective view of my improved nut-lock, showing thehinged recessed plate swung outward orraised. Fig. 2 is a. frontelevation of the same, showing the hinged recessed plate swung down onthe fixed plate. Fig. 3 is a sectional plan view of the same on the linew 00, Fig. 2, the hinged recessed plate being swung outward.

The plate A is provided near one end with an aperture to drop over thethreaded end of the bolt B, and with two longitudinal slits,

from the other end, forming theoutertongucs, (J, and a middle tongue, D.The outer ends of the tongues O are bent to form hinge-loops O, or arebent around the ends of a pivot, K, projecting from the ends of ahingeloop, H. The middle tongue, D, is provided with an aperture, D,near the point, through which aperturea screw or nail or stud is passedinto the object on which the plate A is held, to prevent the plate Afrom turning on this object. A plate, E, is provided at one end with arecess, F, slightly larger than the nut G, and at the opposite end thisplate E is provided with a central hinge-loop, H, fitting in between thehinge-loops O O. The plate E may be cast with a pivot projecting ateachend of the middle part, H, of thejoint for taking the place (Model.)

of the pivot or pintle K; or the hinge may be constructed in any othersuitable manner, so that the two parts will not be disengaged. The outerend of the hinge-joint H is provided with a squared camprojection, J,resting against the middle tongue, D, of the plate A. The plate E isheld in place,when raised or folded down upon the plate A, by thesquared cam-projection J resting against the middle tongue, D, of theplate A, and by the tongues 0 being flexible and bearing upon the pivotof the hinge.

The plate E may be provided with an aperture in place of the recess F.

The bolt B having been passed through the object, the lock is applied byhaviugthe plate E raised, and the aperture in the plate A being droppedor placed over the protruding or threaded end of the bolt B. Then thenut G is screwed on the threaded end of the bolt, and is turned downtight upon the plate A, and is then in position to receive or pass intothe recess F in the plate E when this plate is folded down and restingupon the plate A, thus preventing the nut from turning, and therebylocking it.

l have described the look as applied to one nut; but it can be made fortwo or more nuts above or in line with each other.

I may make the-outer tongues, O, fixed and the middle tongue, D, aspring-tongue, and in this case this tongue D must be provided with ahinge-loop, and the two hinge-loops on the plate E, at each end of thehinge-loop ot' the tongue 1), must be provided with can1-pr0jections;but this construction is a. mere colorable variation of the constructionshown, which is preferred.

I am aware that a nut-lock consisting of a hinged locking-plate providedwith a projection at one end, and pivoted to a spring connected to thefish-plate, which spring acts upon said projection and holds the platein position, has heretofore been employed, and[ therefore lay no claimto such construction, my invention being confined to the constructionpointed out in the claim.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a nut-leek, the plate A, provided with a ing' cam-projection J andthe pintle K, subbolt-hole at one end, and at its opposite endstantially as and for the purpose set forth. with the tongues 0, having"sleeves O at their ends, and intermediate spring-tongue, D, the WILLIAMMILLEI 5 said spring-tongue being integral with said I \Vitnesses:
